WHEN THE MOON TURNS TO BLOOD digs deeply into the horrific tale of the murder and mutilation of two innocent children by their Doomsday Mother, Lori Vallow and her husband, Chad Daybell. Was it simply a love affair gone wrong, a story of sexual lust so intense it drove two people to kill? Or was it something far more sinister? Join me as I interview author and journalist Leah Sottile who in her book explains the who, what, when, where and how of this yet unsettled case. The why... is up to you.

The Petersons seemed the ideal couple, well-respected, prosperous, and happy. All that came crashing down in December of 2001, when Kathleen apparently fell to her death in their secluded home in an exclusive area of Durham, North Carolina. But blood-spatter evidence and a missing fireplace poker suggested calculated, cold-blooded murder. Her trusted husband, Michael, stood accused. To bolster their case, prosecutors introduced evidence at trial that sixteen years earlier, Peterson was the last person to see his neighbor alive before she was found dead at the bottom of a staircase in her home in Germany.

Attending the trial and having intimate access to the families and trial exhibits, award-winning journalist Diane Fanning's Written in Blood spins a heart-wrenching true crime tale that's been the subject of an acclaimed HBO TV documentary, "The Staircase."

Babbling brooks, breathtaking mountain views, the endless sounds of nature. That’s what comes to mind for most of us when we think about National Parks like the Grand Canyon and Acadia National Park in Maine. But these wonderful and pristine escapes have a dark side as well. They are perfect places to commit a murder. Join me as I speak with nature writer, and friend, Randi Minetor as we delve into her series of books on death in National Parks…many by murder!

In the criminal justice system, the People are represented by two important groups: the police who investigate crime and the District Attorneys who prosecute the offenders.

I think it’s safe to say that most of you are familiar with that opening to the successful TV show LAW AND ORDER. But the Defense Attorney is an equally essential party in our Criminal Justice System. It’s funny. When we are accused of a crime, rightly or wrongly, we want an attorney to protect our rights. But what about a serial killer? What are their rights? Do they have any? One attorney who believed a serial killer has an equal right to counsel is Jim Potts, who chronicled his moral and ethical conflict in his book “Defending a Serial Killer” and joins us now on MURDER MOST FOUL.

“Beyond suspicion” and “hiding in plain sight” are two phrases that have been used to describe countless serial murders, that is… before they are caught. Many have led mundane lives that allow them to remain under the radar throughout their reigns of terror. But not Russell Williams, who was by night a rapist and killer, but his day job was that of Colonel in the Canadian Airforce, tasked with flying World dignitaries around Canada, including Queen Elizabeth II and President Clinton. Listen in as I interview author Alan R. Warren and we try to unravel this fascinating case of deception and depravity.

As the ad goes: “You’re in good hands with ALLSTATE,” but not if you are Betsy Faria. The brutal murder of Betsy Faria, on December 27, 2011, set off a maelstrom of events that resulted in an innocent man's imprisonment and another man's death. It would take a decade to unravel all the misdirection in the Faria murder case, the misconduct of the prosecution team, and the insidious mind of a murderer that St. Charles County Prosecutor Tim Lohmar called "The Worst of the Worst!" Betsy Faria was stabbed over 55 times. The murder scene was staged in an effort to frame the victim's husband Russell Faria. Through an investigative trial filled with perjury, tainted evidence, and misdirection, Russell was found guilty and spent 3 1/2 years in prison before his tenacious lawyer won him a second chance. It was during that second trial that the shadows fell away and the real murderer, Pam Hupp, was revealed. But, before they could bring her to justice, several people would be stalked as potential victims, and one man would eventually lose his life in her effort to deflect suspicion from herself. Along the way, her mother mysteriously plunged from her third-floor balcony and died. And at the bottom of it all…pure greed!

Rebecca Pittman has written a book more comprehensive and riveting than any documentary or made for T.V. movie and she joins me now on Murder Most Foul to share with us COUNTDOWN TO MURDER: PAM HUPP (Death Insured).

On June 25, 1973, a seven-year-old girl went missing from the Montana campground where her family was vacationing. Somebody had slit open the back of their tent and snatched her from under their noses. None of them saw or heard anything. Susie Jaeger had vanished into thin air, plucked by a shadow.

“ShadowMan,” by Ron Franscell, is a pulse-pounding account of the first time in history that the FBI’s Behavioral Science Unit created a psychological profile to catch a serial killer. Ron Franscell joins me on Murder Most Foul.

QUESTION: What is better than an exciting True Crime Story? How about 13 such stories in one book. Award winning author Michael Benson has penned just such a book, DARK ROSES and joins me today on Murder Most Foul.

The ancient and oft quoted Hippocratic oath exhorts all doctors “to do no harm.” Technically the exact words are: “I will abstain from all intentional wrongdoing and harm.” It also states that “Neither will I administer poison to anybody.” One Victorian gentleman in England, who did not get the memo, was Dr. William Palmer, who, in the mid-19th century, although tried for only one murder, is purported to have poisoned several individuals. Among his alleged victims: his wife, his mother-in-law, his brother, and four of his own children and anyone he managed to take out a life insurance policy on with himself as the beneficiary.

Journalist and author Stephen Bates wrote a book on the man Queen Victoria called “a black leg” in her diary, entitled THE POISONER and he joins us on Murder Most Foul.
